  • android python full integration

    - by Grzegorz Oledzki
    Is there a way to fully integrate Python with Java code on Android platform? Yes, I saw the question about running Python on Android and Android Scripting Environment (ASE). But that doesn't seem to be enough (correct me if I am wrong). I wanted to be able not only to invoke a Python script from within Java code, but have a full integration. The feature I need the most is the ability to have a state of execution of python code saved and be able to run several parts of code on demand against the same execution state. On JavaSE I would rely on Jython. I believe its simplest example shows it all (and some other features too, like something I would call variable state introspection): http://www.jython.org/archive/21/docs/embedding.html PythonInterpreter interp = new PythonInterpreter(); System.out.println("Hello, brave new world"); interp.exec("import sys"); interp.exec("print sys"); interp.set("a", new PyInteger(42)); interp.exec("print a"); interp.exec("x = 2+2"); PyObject x = interp.get("x"); System.out.println("x: "+x); System.out.println("Goodbye, cruel world"); Is it possible on Android? Is ASE a way to go?

  • Which single IoC/DI container would you recommend using and why?

    - by Rob G
    I'm asking this question because it's a good way to gauge how the community at large feels about the various containers/frameworks and why. Also, whilst my expertise may lie in .Net development, I am very interested in which frameworks are popular (and why) in other languages. If I feel the need to start digging into Java for instance, then I'd like to hit the ground running with good (comfortable) knowledge that I'm starting in the right direction. Does Ruby even need one with all its magnificent dynamicism? I have my own opinions on the .Net front, and will probably add my own personal favourite in an answer below, but I'm interested in all languages and opinions here. With all that in mind, could you please state only one IoC/DI framework that you use and recommend with the language of choice (Java/Ruby/.Net/Smalltalk etc.) and your reasoning for your choice, and if someone has already answered your particular flavour, then you can just vote it up and add comments to it so that anyone looking for advice in future and see which frameworks are more than likely to work for them once they read your reasoning. I'm hoping that over time, the best ones will bubble up to the top. I realise that this question doesn't have only one correct answer, so I won't be choosing one - the community will decide which framework gets the most votes and why. Of course, if you really feel strongly opposed to a particular brand, you could take the reputation hit and vote it down too, and this question can serve as a true wiki-style entry for research into this field. Remember, only one IoC per answer you write please - if you feel the need to promote two frameworks, then write two answers with your reasoning inside for each choice - then others in the community can agree or disagree with you.

  • Sony Bravia KDL-32L5000 PC resolution slightly off.

    - by user18818
    Hi, I have a PC running two Nvidia 8500 GTs in SLI mode and I am trying to use my TV in dual mode. When I switch the TV to PC the screen is nearly centered with a slight offset. All resolutions are effected from 800x600 all the way up to the TVs native 1360x768. I have tried with SLI on and off and have PhysX turned off as well as I thought that might have an effect. I am running Windows XP 64-bit SP2 DirectX ver 9.0c Nvidia driver version 181.22 Any other information please let me know. Thanks in advance.

  • Calling method after view has loaded

    - by iamdadude
    My iPhone app allows for users to type in their usernames and passwords so that they can login. When they login once, their usernames and passwords are saved so that users don't have to type it in again. My problem is, when the app starts again, it immediately starts logging them in, leaving the interface completely black. How would I go about calling my login method AFTER all the UI methods are loaded?

  • GCC ABI compatibility

    - by Fredrik Ullner
    As far as I've understood, it is not possible to link libraries that use different versions of GCC's Application Binary Interface (ABI). Are there ABI changes to every version of GCC? Is it possible to link a library built with 4.3.1 if I use, say, GCC 4.3.2? Is there a matrix of some sort that lists all the ways I can combine GCC versions?

  • In languages which create a new scope each time in a loop block, a new local copy of the local loop

    - by Jian Lin
    It seems that in language like C, Java, and Ruby (as opposed to Javascript), a new scope is created for each iteration of a loop block, and the local variable defined for the loop is actually made into a local variable every single time and recorded in this new scope? For example, in Ruby: p RUBY_VERSION $foo = [] (1..5).each do |i| $foo[i] = lambda { p i } end (1..5).each do |j| $foo[j].call() end the print out is: [MacBook01:~] $ ruby scope.rb "1.8.6" 1 2 3 4 5 [MacBook01:~] $ So, it looks like when a new scope is created, a new local copy of i is also created and recorded in this new scope, so that when the function is executed at a later time, the "i" is found in those scope chains as 1, 2, 3, 4, 5 respectively. Is this true? (It sounds like a heavy operation). Contrast that with p RUBY_VERSION $foo = [] i = 0 (1..5).each do |i| $foo[i] = lambda { p i } end (1..5).each do |j| $foo[j].call() end This time, the i is defined before entering the loop, so Ruby 1.8.6 will not put this i in the new scope created for the loop block, and therefore when the i is looked up in the scope chain, it always refer to the i that was in the outside scope, and give 5 every time: [MacBook01:~] $ ruby scope2.rb "1.8.6" 5 5 5 5 5 [MacBook01:~] $ I heard that in Ruby 1.9, i will be treated as a local defined for the loop even when there is an i defined earlier? The operation of creating a new scope, creating a new local copy of i each time through the loop seems heavy, as it seems it wouldn't have matter if we are not invoking the functions at a later time. So when the functions don't need to be invoked at a later time, could the interpreter and the compiler to C / Java try to optimize it so that there is not local copy of i each time?

  • is there a faster version of fminbnd in matlab?

    - by kloop
    I am now using fminbnd in Matlab, and I find it relatively slow (I am using it inside a nested loop). The function itself, its interface and the values it returns are great, but when looking into the .m file I see it is not optimized. As a matter of fact, I was hoping for something like that to be written as a mex. Anyone knows of an alternative to fminbnd which works much faster and does not have much overhead?

  • BSOD on windows 7 with SSD during boot after improper shutdown

    - by Bob
    I have a BSOD on windows 7 with SSD during boot after improper shutdown (while windows animation logo is moving). The computer restart imediatly after BSOD, and windows proposes to launch startup repair (if i do it, it takes +-5min and fixes the problem : computer starts normally). However, after any new improper shutdown, i got the same problem. Remarks: If i unplug, re-plug the SSD whyle system is shutdown, i have the same problem. If i reproduce the situation with old HDD, i havn't the problem Previously, i had a different problem: BSOD when waking up after sleep, which was fixed by installing drivers (ethernet, usb, graphic card) I have made ram chech and ssd check and found no problems Starting with safe mode after improper shutdown causes a BSOD at loading of classpnp.sys Configuration: System: HP compaq 8510p SSD: OCZ vertex-2 2.5 Boot options: SATA native mode - Enable, HDD transalation mode - LBA-assisted

  • Robust and easy to implement serial bus (automotive application)

    - by JcMaco
    What serial communication bus would you use in a automotive embedded system if your main selection criteria were: * Electrically robust * Slow speed (32 kb/s) * Easy to program * Easy to interface with microcontrollers It won't be transferring much data, but it will need to be transferred periodically at high speed (100 - 500 Hz). I find that RS-232 is just not reliable enough if you have noise in your ground line. CAN-bus seems interesting, but I have no experience with it. We are currently interested in a combination of AVR AT90CAN128 microcontrollers.

  • Do console apps run faster than GUI apps?

    - by omair iqbal
    I am relatively new to world of programming. I have a few performance questions: Do console apps run faster than apps with a graphical user interface? Are languages like C and Pascal faster than object oriented languages like C++ and Delphi? I know language speed depends more on compiler than on language itself, but do compilers for procedural languages produce faster code than OO ones (including C++ compilers that can produce C code)?

  • 1 oracle schema support large reques per day , is this safe ?

    - by Hlex
    I 'm java system designer. As we have large project to do tightly, Those projects are java api without webpage. I design to create general flow engine to support all project. This idea use 1 oracle schema , having general transaction table . And others control routing table. They all nearly complete. But DBA Team concern that he is suffered to maintain very large request to 1 schema. 1 reason is if there are problem is some table. He must offline tablespace to fix. This is problem because all project will be affected. I try to convince by split data of each table to partition by project_code & "month number to delete" . Eaxmple partition: PROJ1_05 PROJ1_06 PROJ1_07 PROJ2_05 PROJ2_06 PROJ2_07 and all transaction table will store on its partition. So, If there are problem on any part of tablespace then he should offline some partition and another project with use same table should able to service Transaction per day should around 10Meg Record per day. Is this a good idea? If I must use 1 schema, what is strategy to do? Do you have any comment?

  • BeanDefinition class removed in Spring 4?

    - by mushtaq
    I am trying out the new Spring 4 release, and I found out that the BeanDefinition interface has been removed, if so what is the replacement class we should use in a scenario where we define a scope for a bean ? Prior to Spring release of 4 you could do this. @Bean @Scope(BeanDefinition.SCOPE_PROTOTYPE) class MyBean{ ... } EDIT As of Spring 4, can't you specify the spring bean scope in the @Scope Annotation, the only option given is to add a string and then the ProxyMode ?

    On lots of sites now, you can see a Facebook "Like" Button. - When depressed, it changes background color. - When mouse-overed, it allows you to write some additional text I love this interface - lightweight action, but allow for expression of more data if the user wants to. Anyone has written a similar plugin?

  • iPad App: Simple Launch View -> SplitViewController

    - by Aurimas
    Hello, I want to create an iPad app that would have a simple view at launch with buttons to different components of the app. Each button then could open up a splitviewcontroller type views. (Interface similar to WebMD: http://itunes.apple.com/us/app/webmd-for-ipad/id373185673?mt=8) I was reading online that Apple does not allow splitviewcontroller inside other controllers (like NavigationController). How do I solve this? Thanks!

  • Radeon hd 6570 black screen

    - by Sho
    I got some problem with new graphic card. Every time I use AMD Catalyst drivers on Windows or Linux, screen repeatedly goes black. This usually shows u when i open new cards in a browser, resize a window or run a program. Card runs smoothly on basic drivers but this means low resolution. 1940x1080 is native for my monitor so it causes a lot of problems. I've got a 600W Deus G1, so the power is not the problem. Maybe its a silly question, but would going form a vga cable to hdmi help to improve this situation? If not, can it be caused by slow processor or old mainboard? Im getting kinda confused about this whole thing...

  • How to develop JSP/Servlets Web App using MVC pattern?

    - by A.S al-shammari
    I'm developing a JSP/Servlets web app (no frameworks). I want to use MVC pattern. I designed my project like this : Controller :a servlet that reads a request, extracts the values,communicates with model objects and gives information to a JSP page. View : JSP Pages. Model : Java Classes / Java Beans .. etc . The problem : Index.jsp is the starting point (default page) in my web site. So, the Index.jsp becomes the controller to parse the request! .For example , the following request : index.jsp?section=article&id=10 parsed in index.jsp as following : <div class="midcol"> <!-- Which section? --> <%String fileName = request.getParameter("section"); if (fileName == null) { fileName = "WEB-INF/jspf/frontpage.jsp"; } else { fileName = "WEB-INF/jspf/" + fileName + ".jsp"; } %> <jsp:include page='<%= fileName%>' /> </div> Here, I can't force the servlet to be a controller .. because the index.jsp is the controller here since it's the starting point! Is there any solution to forward the request from index.jsp to the servlet and then go back to index.jsp ? Or any solution that achieves the MVC goal - the servlet should be the controller - ? I'm thinking of making a FrontPageController servlet as default page instead of index.jsp ! but I don't know if it's a perfect idea ?!

  • Management VLAN Cisco Catalyst

    - by cha789
    I have configured a couple of VLANs on a Cisco Catalyst switch, i will put all the ports that clients is connected to, into these VLANs. I want to configure the native VLAN [vlan 1] as management VLAN so i can use a telnet client to connect to the switch. How can i block all but one specific IP-address to telnet into the switch? As i understand vlan 1 has many task regarding different protocols and i do not want to break that but only allow one specific IP-address to connect to the switch with a telnet client [actually the gateway ip address of the switch].

  • Fabric "TypeError: not all arguments converted during string formatting"

    I have the following fabric task: @task def deploy_west_ec2_ami(name, puppetClass, size='m1.small', region='us-west-1', basedn='joe', ldap='arch-ldap-01', secret='secret', subnet='subnet-d43b8ab d', sgroup='sg-926578fe'): execute(deploy_ec2_ami, name='%s',puppetClass='%s',size='%s',region='%s',basedn='%s',ldap='%s',secret='%s',subnet='%s',sgroup='%s' %(name, puppetClass , size, region, basedn, ldap, secret, subnet, sgroup)) However when I run the command: fab deploy_west_ec2_ami:test,java I get the following Traceback: Traceback (most recent call last): File "/usr/local/lib/python2.6/dist-packages/fabric/main.py", line 710, in main *args, **kwargs File "/usr/local/lib/python2.6/dist-packages/fabric/tasks.py", line 321, in execute results['<local-only>'] = task.run(*args, **new_kwargs) File "/usr/local/lib/python2.6/dist-packages/fabric/tasks.py", line 113, in run return self.wrapped(*args, **kwargs) File "/home/bcarpio/Projects/githubenterprise/awsdeploy/fabfile.py", line 35, in deploy_west_ec2_ami execute(deploy_ec2_ami, name='%s',puppetClass='%s',size='%s',region='%s',basedn='%s',ldap='%s',secret='%s',subnet='%s',sgroup='%s' %(name, puppetClass, size, region, basedn, ldap, secret, subnet, sgroup)) TypeError: not all arguments converted during string formatting I am not sure I understand why.

  • What IDE setup and workflow is used for OSGi development?

    - by Falx
    I made quite a few easy OSGi test projects in Eclipse RCP. My typical workflow would always be: Make 3 different projects: APIproject, Clientproject and Serverproject Edit the MANIFEST.MF of APIproject to export the api package Edit the MANIFEST.MF file of Clientproject and Serverproject to add the required API package Choose "Run as..." "Plugin Framework" OSGi console starts in eclipse and everything seems to work I also tried wiring things by using Declarative Services, which worked well like this too. Now recently I wanted to try out iPOJO. The problem is that I get the feeling that I've been doing my OSGi development the wrong way. Can it be that I should instead make 1 project en make it work like no OSGi is involved. And then afterwards, just export each package to its own bundle by means of (for instance) the BNDL tool? Should development be done in a normal Eclipse (java, not RCP) or any other java IDE for that matter? So that's why I have these questions: What IDE setup is normally used to develop OSGi with iPOJO? And what is the normal workflow to be used when developing OSGi projects (maybe with iPOJO)?

  • Access Request Body in a WCF RESTful Service

    Hi, How do I access the HTTP POST request body in a WCF REST service? Here is the service definition: [ServiceContract] public interface ITestService { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "EntryPoint")] MyData GetData(); } Here is the implementation: public MyData GetData() { return new MyData(); } I though of using the following code to access the HTTP request: IncomingWebRequestContext context = WebOperationContext.Current.IncomingRequest; But the IncomingWebRequestContext only gives access to the headers, not the body. Thanks.
